This is because of the wonderful revolution in Digital Photography. We have digital cameras such as the beautiful Hassleblad that can take 20+ megapixel photographs and have 40+gigabyte hard drive built in for the professionals use right down to mobile phone and PDA’s that take 1-2 megapixel photographs. But how do we know how many megapixels we need in our camera? Digital cameras are affordable to most people, plus you save on purchasing film and processing costs. You are able to see you images immediately. Sounds fantastic doesn’t it! There are some costs that we do not consider. Digital Cameras can go through batteries in no time. We need memory cards to capture and store our images. We have to transfer the images from our camera to a computer or image output device. We take so many images and file them away on our computer systems or share them with friends via email, but how can we make paper copies of our images and display them in a way that will make them stand out? This is what we will discover in the follow pages. We will do this in parts. First we will start by becoming familiar with and understanding digital cameras. We will then look at some basic photographic concepts for capturing better digital images. We will do some basic editing of our images in our digital darkroom. From there we will discover the best output for our finished images. Section 1: Digital Imaging. The Terminology. There are many new terms that we will come across when looking at digital cameras. Lets get an understanding of the jargon that we really need to know to get us started. Pixels Photographs on a computer are made up of thousands of tiny squares called picture elements or pixels for short. Each pixel holds information about the exact colour and tone for the image. The more pixels an image has the larger you can print the image. If you enlarge an image and start to see little squares then what you’re seeing is the individual pixels as demonstrated in Fig 1. Figure 1: the little squares are individual pixels. Megapixels and Resolution The number of pixels that a camera can capture indicates the quality of the image that it can capture. The higher the number the better the quality of picture that you will be able to take. Lower megapixel cameras are great for emailing images to others, posting on web sites and using on mobile devices, but the print quality is often disappointing. The higher megapixel cameras allow for excellent print quality and will allow you more freedom to edit the images, but you will require more storage space for the images and the cameras will cost more. Resolution is the measurement of the output quality of an image. DPI(dots per inch) for print and PPI(pixels per inch) for screen. Digital and Optical Zoom Optical zoom is a true zoom function. It brings the objects closer to you using the optics of the camera Digital zoom enlarges a section of the image so it appears closer. The quality of a digital zoom is the same as if you crop the image using photo editing software. So what does this mean? Disregard digital zoom qualities on a camera. Optical zoom is what you want if you want to have true zoom capabilities. Aperture size. Apeture refers to the size of the hole in the lens that lets the light through to the film or sensor. It is used to regulate the amount of light entering into camera for an exposure. Aperture will also affect the depth of field. The larger the Aperture size the more light that gets in through the lens and the shallower the depth of field. You can use the apeture to get better pictures in a variety of lighting conditions. With a large aperture you may not need flash, allowing for a more natural look using the available light. We will look at Aperture in more detail in the taking photographs section of this text. Shutter speed The shutter speed is the amount of time that the light is allowed to enter through the camera lens. The amount of time will influence the depth of filed. It will also effect the sharpness of moving objects in your photo. A slow shutter speed will make motion blur. A fast shutter speed will capture the action crisply and clearly. Noise Noise in digital images is tiny specks of random colour that show up in an image. It’s the digital equivalent of film grain and can be caused by long exposure and/or high ISO images taken with digital SLRs. It can also be caused by the camera being hot and from using the digital zoom(yet another reason to avoid it!). When looking at the 2 images below not much appears different until you enlarge the images when it is very obvious that the image on the left has lots of noise. Figure 2 examples of noise 10 Storage Media Digital Cameras come with a slot for a variety of media cards. Some digital cameras also have on board memory. Figure 3 Sandisk Storage Media The bigger the memory card the more storage space you will have and the more images you will be able to take. Purchasing spare cards can be a great benefit if you use your camera regularly or if you use the high quality features of your camera. Think of your camera’s media just like a film; if you do run out you can simply insert another one then download them all at a later date. Sensors Digital cameras use small sensors to capture the light waves of the image before transferring it to its memory. This is like the negative of a film camera. The commonly used types of sensors are CCD (Charged Couple Devices ) and CMOS (Complementary Metal Oxide Semiconductor). CCD technology has been around for over 2 decades and dominated high quality sensor applications until about 2000. It was then that Canon introduced the Canon EOS D30. CMOS was considered to have intrinsically higher noise qualities but like most IT related technology, CMOS has been advancing rapidly. It delivers better performance including very low noise and lower power consumption (giving better battery life) at lower cost. Exercise 1 Go to the following web sites and find out more details about Sensors. http://www.creativepro.com/printerfriendly/story/21600.html http://web.canon.jp/Imaging/cmos/index-e.html http://www.normankoren.com/Tutorials/MTF7. html#Digisensors Try and find out what the BAYER filter is? Connectivity Connectivity refers to how we will get the data from the camera on to the computer. Most cameras attach to the computer via USB. Firewire and wireless connections Figure 3 4 Lexar Card Reader 11 are also becoming common place. Card readers for multiple types of memory cards are also available and are proving to be popular. Many computers are now becoming available with inbuilt card readers. We also have some ranges of cameras now that dock directly to the printer so we can instantly print our photos. The Kodak Easy Share series is a great Figure 5 Kodak Easy Share System example of this method. File Format. There are three types of file formats that digital cameras can capture. The most commonly used one is JPG. (Joint Photographic Expert Group). Tiff and Raw are available on the higher-end cameras. Digital cameras use their own processors to take the raw data collected by the camera and process that data into a JPG format. Each company uses their own standards to do this. The RAW format keeps the data as an unprocessed file. This allows the photographer more control over the way the data is processed. The RAW format is still not fully standardised so each camera manufacturer has their own software for editing RAW files. Some manufacturers have worked with Adobe to create converters so their raw file format can be converted to a DNG(digital negative file). This allows the data to be manipulated in Adobe Photoshop - the current industry standard for photographic software. RAW files are much larger then JPG files because of the additional information that they hold. Digital cameras have different settings for size of JPG files which can be confusing. An example of this is a camera that has settings such as fine, superfine and normal. These settings are all capturing the same file type, but different resolutions. Kodak cameras use logical names such as email, good, better and best. Canon use small, middle 1, middle 2 and large. Check your cameras manual to see the different resolution and file types available to you. 12 White balance and Colour Temperature To understand white balance you need to understand colour temperature. When we look at a scene our eyes automatically adjust for colour temperature because our brain knows that the colours are not represented to us correctly and our brain overrides what we see. You might have seen images where they look a bit yellow or blue. Colour temperate is a way of measuring the quality of the light and the colour that different light sources can cast on an environment, which, in turn can cause a colour cast. Film cameras catch the colour casts and the colour cast was removed at the time the image was printed. Digital cameras have an automatic white balance correction system that acts like our brain does, so that you do not have to worry to correct this after the image is taken. Some digital cameras have specific white balance settings that we can use to tell our camera what lighting type we are using. This can also be used to create some very interesting effects. Burst Mode Many digital cameras have a burst mode or continuous shooting mode. This mode allows the taking of a sequence of images in rapid succession while holding down the shutter button. Images are held in the camera’s buffer then saved to memory. This is a great feature when photographing fast moving subjects so we can take a series of images and then choose the best. This features is not always available when using the flash as the flash needs time to regenerate. Focal Length The focal length refers to a measurement of the lens. This measurement will determine the width of angle or zoom capabilities of the lens. The focal length is the distance between the back lens element and the focal plane(the area of the camera where the lens focuses on the film or digital sensor). In SLR(35mm) format, lenses with a focal length of approximately 50mm are called normal (standard), lenses with approximately 35mm or less are called wide-angle, and lenses with a focal length of more than approximately 70mm are called telephoto lenses. In portraiture it is recommended to use a 105mm lens as 13 it gives the most accurate representation. Depth of Field Making the main focus of the image sharp and the background out of focus gives us depth of field. We can control the depth of field by controlling the aperture. A large aperture will narrow our depth of field. A small aperture will increase our depth of field. Digital cameras often have a landscape and portrait mode. These demonstrate the use of depth of field as the portrait mode is preset with a narrow depth of field forcing our focus toward the subject. The landscape mode has a wide depth of field and therefore keeps as much as possible in focus. The picture in figure 6 demonstrates depth of field. You can clearly see that the dog and the grass under the dogs feet are in focus but the background is out of focus. This makes us ignore the out of focus and concentrate on the dog. Figure 6: Example of Depth of Field 14 Maximum Print Size vs Megapixels. The following is a guide as to what size print can be printed from what megapixel camera. 6+ MP 5-4 MP 3 MP 2 MP 76.2 x 101.64 40cm x 50cm 28cm x 36cm 20cm x 25cm This guide is for images that have not been cropped or the digital zoom was not used when shot. Manipulated images may mean smaller print sizes. Battery munchers Digital cameras need power. Many have their own power source but some use traditional Alkaline Batteries. If unaware of the problem you might find that the money you save in buying film and processing is spent buying batteries for your camera. Most digital cameras are battery hungry but there are things we can do to increase the battery life. 1. If your camera has a viewfinder, use it. Refrain from using the LCD monitor when you are taking your photos. Do not leave the LCD monitor on for any 2. length of time. 3. Only using the monitor for playback, erasing, etc.. Turn the camera off unless your using it. With any digital camera, it would be wise to either get a camera with a rechargeable pack or use Lithium batteries. 15 Digital Cameras When comparing digital cameras you must first decide what the camera will be primarily used for. Will it be used for snapshots around the home? Will you need to print large images from the files? Are you going to take up photography as a hobby? Some examples of the considerations you might need are as follows: Do you want to Print enlargements of your images? You will need Higher resolution. Do you want to Publish on the internet and email to friend? You will need Lower resolution. Do you want to Take photos while travelling? You will need more storage. Do you want to Get in closer to your subjects? You will need Optical zoom. Will you be taking pictures of small items like flowers, coins? You will need Macro features. Do you want to take photos at night, indoors, by candlelight? You will need Low Light features. Will you be taking pictures of fast moving objects like race cars or small children? You will need a Fast burst rate. Do you want to make sure that the money you save on film and developing doesn’t just end up getting spent on batteries? You will need a camera with rechargeable Lithium-Ion batteries or similar. Do you want to stick within your budget? You need to shop around and know what you want. Exercise 2: Write down a list of things you want to do with your camera. Work out for each of those wants what your features your camera would need to have. 16 Understanding Camera Specifications We are starting to understand what we want in our camera, but how do we find out this information? The best way is to have a look at the specifications of cameras that are available on all brand name cameras web sites. We are going to investigate 3 digital cameras. These will be The PowerShot A430, the Digital IXUS 55, and EOS 350D Twin Lens Kit B, all from the Canon series of cameras. Let’s look first at the specification for the Canon PowerShot A430 http://www.canon.com.au/products/cameras/ digital_compact_cameras/powershota430.html This 4 megapixel camera is cheapest in the canon range of digital compact Figure 7 Canon Powershot A430 cameras. Using the specification section from this web page we can find out the nitty gritty details about this camera. The following are main sections that we want to look at so we can ascertain what this camera would be good for. The Sensor information This camera uses a CCD sensor that is 4 megapixels. The size of the sensor is 1/3.2 inches in size and the filter array it uses is the primary colour Bayer filter. These details were explained in the technology section regarding sensors. If they don’t make sense go back and have another look at the definition of sensors. 17 The Lens components We know from the terminology section of focal length that the lens can be wide, standard and telephoto. We are interested in what the optical zoom is on this camera. Digital zoom is irrelevant. Its focal length, aperture, shutter speed, and sensitivity allow us to compare it to other similar cameras. It also tells us what the focusing range is, i.e. how far you need to be from the subject for the subject to be focused on. This camera has a focal length starting at 39mm and at maximum zoom 156mm. This would make this lens a standard lens with some telephoto capabilities. For depth of Field we look at the apeture and this camera has an aperture of 2.8 to 5.8. at 2.8 we would have very little depth of field. At 5.8 we would narrow the depth of field. 18 Control/Balance The Control/Balance section explains to us how the camera measures the incoming light. This camera also has different white balance modes, so if it’s a cloudy day we can modify the camera for this and the camera will compensate the colour temperature for it. LCD Viewfinder The Viewfinder is the hole that you look through to see what your photographing. The LCD monitor is the small screen that you can use to review your images. Some cameras use the LCD Monitor as the viewfinder as well as for reviewing images. Using a viewfinder is a good idea when taking photographs because the LCD screens use up considerable battery power. If using AA alkaline batteries this will make a big difference. This is a common mistake made by owners of digital cameras. They often say that they can’t understand why their camera goes through so many batteries. 19 Flash Modes Knowing the range of your flash is important as is the different options available in the flash modes. All cameras tend to have a flash on and flash off function but the other functions are useful for other purposes. In particular the fill flash function is an excellent option which will be discussed further later in the notes. That option is not available on this particular model. Selectable Shooting Modes Shooting modes allow you to automatically select settings for different purposes without having to fully understand how camera manual settings such as aperture, exposure, F stops etc. work. These settings give amateurs the power to capture well exposed and in-focus images. 20 Image Recording Format This shows the file format that is available. This camera saves in JPEG format with 3 different compression levels. The Large images are larger files in size but are better in quality. You can decide the quality of the image you’re taking dependant on what the images might be used for. For instance family snap shots might be normal but special family group photos might be used as enlargements so would be shot at the large setting. The continuous shooting information tells you how many shots the camera does in a continuous sequence. This is important for fast moving and action type photography. The more and the faster the better. This camera comes with the ability to not only choose the compression level (super fine, fine or normal), but you can also choose the image size, making your choices for storage many. This camera comes with a supplied memory card 16 Megabytes in size. 21 The Interface The interface is how the camera connects to the computer system. In this case the camera can be plugged into the system via a USB port. It uses a SD Memory Card or multimedia card that holds 16 MegaBytes of information. This type of card is available in larger sizes and spare cards can be used just like you would have changed your film cartridge in traditional film cameras. This camera can be used with the supported operating systems which are the most popular current platforms. Software is also supplied to make access to the camera easier. Determining the power area is very important. You need to know what type of battery your camera uses and how many shots the battery will last for. This camera uses AA alkaline batteries but also has an optional charger adapter. The compact range of digital cameras would be fine for snapshots. The point and shoot style of camera is easy to use as it comes with fully automatic functions. You can enlarge images up to 28x35cm. The images would be fine for emailing to friends 22 or making online photo albums. You wouldn’t want to enlarge any of these images to poster size as the quality may begin to deteriorate. You would also find that cropping these images will quickly reduce the quality as well. For the price they are a good buy for the average camera user. Exercise 3 Go to http://www.energizer.com/learning/batterycare.asp or http://www. duracell.com/au/main/pages/product-information-battery-care-disposal.asp and have a look at the battery care information Have a look at some of the product data sheets for the Occupational health and safety information about handling, storage and disposal of batteries at http://data.energizer.com/Static.aspx?Name=ProductSafety or http://www. duracell.com/oem/Safety/. Exercise 4 So we’ve now had a look at some of the different specifications on a low end camera. How would we choose between different cameras in this price range? The Matrix! The Matrix was not just a popular movie; it is also a very useful tool that we can use in determining and judging similar products to make an educated decision on the best product for our needs. A matrix lists the specifications that are important to our decision and then compares common specification of similar products. Using the following matrix compare the Canon A430 to other cameras in its price range and see which you would buy. Important Features Canon A430 Choice 2 Choice 3 cost Power Source Optical Zoom Viewfinder LCD monitor Flash Modes Flash range Shooting Modes Shooting speed /burst mode image format storage White Balance Control Shooting Capacity 23 Mid Range Cameras. We are going to investigate the Canon Digital IXUS 55. This is also a compact digital Figure 8 Canon camera but is in the mid Digital IXUS 55 range in cost for this type of camera. Lets look at the differences in what features differ from the Canon A430. Have a look at the cameras specifications at the Canon Web Site. http://www.canon.com.au/products/ cameras/digital_compact_cameras/digitalixus55.html. The main difference you will find in this camera is that it does video format as well as still images. The image sizes are larger and the battery is a Rechargeable Lithium-ion battery. This camera still images size and storage capacity 24 So the images are better quality but the files size are larger. This camera comes with exactly the same storage of 16 MB as the Canon A430 The power source Interesting, don’t you think? This camera has video, better quality images and uses a rechargeable battery. However you get less shots on the storage space supplied, and the shooting capacity at full charge is less. So it has some better features and some disadvantages. Purchasing a larger memory card and additional battery would soon overcome these problems. This camera would be great for the same group of users as the Canon A430, those who are looking for a camera that you don’t need to buy batteries for and who would like the added feature of video. Top Range Cameras (SLR) There was not a lot of major differences between the low and mid range cameras. They are very easy to use and reasonably affordable. The digital SLR cameras are a completely different beast. To get the best out of these cameras, you must understand how to use the manual settings on the camera. They have fully automatic features so any one can use them but they are a waste if they are not used to their full potential. Like the point and shoot types of digital cameras, there are also low, mid and high ranges of DSLR. The Canon EOS 350D is in the lower end of the range. A fantastic camera for the amateur 25 or semi professional, with an 8 megapixel CMOS sensor, it would be an excellent choice for good quality prints with excellent enlargement potential. Canon EOS 1Ds mark II body is a camera made for the professional. With a 16.7 megapixel CMOS sensor – this camera can capture fantastic quality prints. SLR cameras have changeable lenses, just like their film counterparts. The EOS 350D comes with 2 lenses, with many others available. The EOS -1 Ds comes with no lens. There are many additional parts and components available for both cameras, many are interchangeable. A vast array of lenses for example are available for the EOS range of cameras that can be used on both of these examples. Figure 9 Canon EOS Figure 10 Canon EOS 1D Lets compare the difference between these two cameras. Below is a table that compares side by side the differences. You can see very quickly the main difference is in the quality of the image captured, demonstrating the professional use of each. The EOS 350D being more affordable but having only half the megapixels of the EOS -1Ds. 26 Image sensor: 8.0 megapixel CMOS sensor; 22.2x 14.8mm effective size Number of recording Large / Fine: 3456 (H) x pixels: 2304 (V) pixels Middle / Fine: 2496 (H) x 1664 (V) pixels Small / Fine: 1728 (H) x 1152 (V) pixels RAW: 3456 (H) x 2304 (V) pixels Sensitivity (equivalent ISO 100, 200, 400, 800, film speed): 1600 (selectable via ISO speed menu) Image data storage: Compact FlashT (CF) card Type I or Type II standard; 1 slot Image compression: JPEG or RAW Image compression Raw / Fine / Normal level: Image storage capacity (with 512mb Large / Fine: approx. 145 flash card): images 16.7 Megapixel CMOS sensor 36 x 24mm effective size Large: 4992 x 3328 pixels; 5.5MB Medium1: 3600 x 2400 pixels; 3.2MB Medium2: 3072 x 2048 pixels; 2.6MB Small: 2496 x 1664 pixels; 1.9MB RAW: 4992 x 3328 pixels; 14.6MB ISO 100-1600 in 1/3stop increments; can be expanded to ISO 50 and 3200 Compact FlashTM (CF) card Type I or Type II standard, SD memory card JPEG or RAW (12 bit) N/A Large 93 images Medium 1 160 images Medium 2 196 images Small 269 image Large / Normal: approx. 279 images Middle / Fine: approx. 245 images Middle / Normal: approx. 466 images Small / Fine: approx. 419 images Small / Normal: approx. 790 images 27 Image storage RAW / Fine: approx. 58 capacity (with 128mb images flash card): Lens: Canon EF and EF-S series, effective focal length 1.6x Shutter: Vertical-travel, mechanical, focal plane shutter with all speeds electronically controlled Shutter speed: 1/4000 sec. - 30 sec.

At the time of writing this the Canon EOS350D with 2 lenses was advertised on the Canon site for $1599.00 Australian Dollars. The EOS-1Ds Back only was $12999.00. That’s a lot of difference in price. From a professional standpoint the extra quality would far out weigh the price asked. A professional photographer would save that difference in film and processing costs alone in the first year of use, but to the average photo buff, it’s probably a bit pricey. The EOS 350D and EOS 1Ds Mark II won top honours at the prestigious Technical Image Press Association Awards of 2005. The EOS 350D taking out best entry level Digital SLR Camera and the EOS-1Ds taking out Best Professional Level Digital SLR Camera. For more information about other winners of these awards see http://www.tipa.com/awa_2005.lasso Exercise 5 Go to other camera manufacturers sites and see if you can find cameras that compare with the Canon 29 Memory Cards We use memory cards for storage on the camera of our captured images. We can use memory cards much like we used to use film in cameras. If we have extra film we can reload the camera and continue photographing without too much interruption. The size of the memory card will determine the amount of storage on our device and how often we might need to reload the camera. In most cases one or two cards will do fine. Most digital cameras taking jpeg photos will hold 100+ photos without too much problem. When we get into the higher megapixel cameras we need both larger memory cards and more of them, depending on what the camera is being used for. SD Memory cards/Multimedia cards These cards are popular for many devices, including mobile phones, hand held games, PDA’s and of course digital cameras. They come in a huge variety of sizes, starting from 256mb right up to 2gig+ cards. For more detailed information about how SD memory cards work and what other types of devices use them go to Figure 11 SD Cards http://www.sdcard.org/ Compact Flash Cards. These cards are larger in size but also available in large storage sizes. These cards hold from 128MB to 4GB+ For the serious professional the more space the better. If you have a look at the prices of some of the range of sizes you will soon see there is a major difference when buying cards. For more information about Compact Flash Cards Figure 12 CF Cards go to http://www.compactflash.org/faqs/faq.htm 30 Exercise 6 Go to the web site www.sandisk.com and from their products select memory cards. Find out the different prices of the SD memory cards and Compact Flash Cards. From the Canon cameras we looked at early, find the type of card you would need for each camera. Under what sort of scenario would an 8GB compact flash card be worthwhile purchasing for the EOS-1Ds camera? Exercise 7 Go to http://www.shortcourses.com/choosing/contents.htm and read the information about choosing a digital camera on this web site. 31 Section 2 Basic Photographic Principals. Composition and Balance Most good photographs have some rules that have been applied. There are those that break the rules but more often than not we can see why good photography is good. By following some of these rules your photography can improve dramatically. Using foreground objects as a point of reference. The art of framing your subject using doorways, overhanging branches, etc can give your image a sense of depth and size. Using objects in the foreground can help establish the size of an object therefore giving a sense of scale. Examples shown in figure 13, 14 and 15 Figure 14 Figure 13 Figure 15 32 Avoid Distracting Backgrounds. When composing your photograph most people are so interested in the main focus of the image that they don’t consider looking past that and seeing what is in the background. Bright colours, signs, and busy backgrounds can be the most distracting. Be especially aware of what is behind your subject when doing portraits as often people will have trees and poles growing out of their heads. Photographs can be improved by simply Figure 16 considering what is in the background of the photo. By moving your subject or changing your angle of view you can often improve them (Fig 16). Choosing main point of interest. Sometimes you know what the main point of interest in your images is but it might not be obvious to others. To many things happening in a photograph can make the main point difficult to determine. Eliminate all the unimportant elements by focusing in on your main point of interest. You can do this by zooming in (Fig 17), choosing a different angle, using depth of field (Fig 18), or moving closer to your subject. Figure 17 Figure 18 33 Angle of view When photographing people it is a good rule of thumb to photograph them at your subject’s eye level (fig 18, 20). For formal portraiture this is very important. If you want to be a bit more creative adjust your angle of view. Photographing things from a different perspective will give you some fun and creative images (fig 18, 21 and 22). You can also Figure 19 exaggerate the size of your subjects using different angles. For instance, to make your pet seem small, photograph from a high vantage point. It will make them look smaller than photographing them at eye level. Figure 20 Figure 21 34 Figure 22 Figure 23: Same subject, different angle Figure 24: Another example of same subject different angle, different lighting 35 Placing subject off center – the rule of thirds. The rule of thirds has been a popular photographic and art concept for many years. Basically you divide your image with imaginary lines that intersect. When the points intersect, you place your points of interest. It is also a good reference for the horizon. There Figure 25 is nothing worse than having a picture cut in half by having the horizon exactly center. It seems to balance the picture having the horizon on the top or bottom third. Figure 26 Figure 27 36 Figure 28 Figure 29 Figure 30 37 Figure 31 Figure 32 Leading Lines Sometimes natural lines will lead you through an image to the main subject. A road, fence, waterline etc can direct the eye. Diagonal lines tend to give a more dramatic look and curved lines are more flowing and graceful. Figure 34 38 Figure 33 Figure 35 Figure 36 Horizontal or Vertical. Don’t always use your camera for horizontal photographs. You can turn it sideways you know!! Experiment with both horizontal and vertical versions of photographs and see what difference it can make. Figure 37 Exercise 8 Search the internet for images that demonstrate the concepts of Using foreground objects as a point of reference, Angle of view, Placing subject off centre – the rule of thirds, and Leading Lines. http://www.alamy.com is an excellent place to visit to find images. Using the images you found, put them in a word document and comment on how each one uses the concepts. Have your lecturer go over your comments to ensure you have a full understanding. 39 Lighting Photography is all about light. Light is what is captured to create the image. The direction or position of light will make changes to how your main subject is seen. Strong light will look very different to soft light, candle light will look different to spot light. Being able to control, or work within the lighting you have available to you is very important. Sunlight - High Front Light This form of lighting is great because most of our scene will be well lit, bright sunny days can bring out the colours of our scene. However, they may cause your subject to squint. High Noon sunlight can create deep shadows under eyes and chins and need you to use fill in flash. If photographing in full sun do so when the sun is not at its highest, mid morning and mid afternoon are both excellent times. Figure 39 Figure 38 Figure 40 Full Flash – Front Lighting. This type of lighting does light the entire scene evenly. It does however lack volume and depth and the scene appears to be flat with few shadows. 40 Figure 41 Figure 42 Side Lighting.-45 degrees Side lighting is lighting that is coming at a 45 degree angle from the side of the subject. It is one of the most used types of portrait lighting. It separates the subject for the background, conveys depth and texture and can be used to emphasize dimension, shape and pattern. It can however be too severe for some subjects. Using a reflector or fill flash can compensate for this problem and produce fantastic results. Figure 43 Figure 44 Figure 45 Figure 46 Figure 47 Figure 48 41 Backlighting Figure 49 This type of light is by far the trickiest to pull off but the dramatic results can be worth your while. By lighting the subject from the back you can simplify a scene by emphasizing the subject as in a silhouette. It can provide a flattering halo in portraits and can add strong shadows in landscapes. One problem that you can come across in backlit subjects is lens flair – light directly entering the lens from the light source. Easily fixed by shielding your camera with your hand, a book etc, just enough to shade the lens but not obscure your view. Figure 50 Figure 51 Figure 52 42 Using Aperture and Shutter Speed. If your camera allows you to control the aperture and shutter speed of your camera you can use this to your advantage. Aperture is set using the fstop on the lens. The wider the lens is open, the more light that gets to the sensor, and the smaller number the f stop is. To control the depth of field we use the aperture set to a high number for a small depth of field and a low number to keep as much in focus as possible. Shutter speed can be used to give Figure 53. Using a fast shutter the feeling of movement or for speed for action shots allows the capturing fast moving action. The water in this photograph to be larger the shutter speed the faster the action that can be caught. Slow shutter speeds can allow us to see motion or movement. You will need a very good digital camera to be able to use these features. Some of the auto features will have these settings automatically set into the camera. Experiment and see what you can create. Figure 54. This image used a slow shutter speed and you can see the children are in motion Exercise 9 Using images from http://www.alamy.com, find and explain the use of the lighting styles described. Add this information to the document you created in exercise 9 and make sure you comment on how each one uses the lighting styles. Have your lecturer go over your comments to ensure you have a full understanding. 43 Light sources Natural Light Natural light has an array of possibilities: from bright sunny days to overcast rainy days to sunsets and sunrise and all the possibilities in between. The secret is to identify the different types of natural light situations and recognise their benefits. Overcast days can be prefect for portraits as there are no harsh shadows or fill flash needed. Rainy days can give fantastic reflections. Soft foggy light will give a different feeling to the same landscape that might look vibrant and crisp on a sunny day. Figure 55 44 Figure 56 Figure 57 Same subject but different natural lighting. See how the full sun gives deep shadows. Figure 58 Figure 59 Figure 60 45 Other Light When looking at our digital cameras we mentioned white balance and colour temperature. When we look at other available light that is man made we come across the problem of colour casts. Fluorescent lights create a green hue, traditional light bulbs (tungsten) create a yellow hue. We don’t see the colour casts because our brains white balance automatically correct this for us. Cameras aren’t that smart, however most do have built in white balance features that compensate for the white balance. Many shooting modes also compensate for these problems. By understanding the different shooting modes on our cameras we can often head off having these problems in our photographs. If you do still have a problem with colour casts it is possible to correct them in our digital darkroom, particularly if we have used raw files. Figure 61: Tungsten Light Figure 62: Corrected Figure 63 46 Flash, fill flash and flash off. Flash allows us to photograph in less that perfect lighting conditions. Always stay within the flash range of your camera. I avoid the use of red eye reductions settings as it can be distracting and confusing to subjects. Instead have the subject look slightly away from the camera or add more light to the area (turn on the room lights!). If all else fails we can fix the Figure 64 red eye problem in our digital darkroom. Fill flash is a much more natural type of lighting as it doesn’t blast the subject with light. It fills in the darker shadows enough to give detail but still gives shape and Figure 65 texture. Best used for sunny days that give strong shadows, backlit images to give some detail and to compensate for any other shadow problems. Flash off captures exactly what you see. Fantastic for those Figure 66 special lighting situations such as low light or the quality of the light is in itself worth capturing. If using flash off you may need a longer exposure time so steady yourself against something and keep your elbows anchored by your side. Figure 68 Figure 67 Figure 69 47 Reflecting Light. Instead of using fill flash, if you have the ability, reflect the light back into the subject to softly fill in those dark shadows. A commonly used technique amongst professionals. Reflectors can be purchased from most good photographic shops or you can use simple things such as white polystyrene sheets, paper/cardboard etc. Fig 70 demonstrates the use of reflection as the silver surface of to table has created a Figure70 reflection of light that has filled in the darker shadows in this childs face. Studio Light Photographers for centuries have been creating their own sources of light. Professional light kits include a number of special pieces of equipment to direct, soften, harden and control lighting situations. Photographic studios are a very dark place, so that the photographer has full control over the lighting environment. Exercise 10 In a search engine look for Australian Professional Photographers. Have a look at the different lighting styles that they use, the different locations, and how they have used some of the concepts discussed earlier such as horizontal vs vertical, slow shutter speed vs fast shutter speed. Think about how they might have created the image. Some of my favourite Aussie’s sites are www.robinsellick.com for fantastic commercial portraits, www.davidsummerhayes.com for fantastic landscapes and fine art photography, www.timwilliams.com.au for portrait wedding examples. All of these photographers I know personally and am a fan of their work. www.aipp.com.au has a list of many other Australian photographers. Exercise 11 Go to http://www.shortcourses.com/using/index.htm and read the information about using a digital camera on this web site. Exercise 12 You now understand how to use your digital camera, how to compose images, and what types of lighting you can use. Using your digital camera try to capture some images using the different settings of your camera, 48 Particularly those that we have discussed in this section such as the different flash options, using reflective surfaces and back lighting. Experiment with your cameras different modes to discover what your camera is capable of. Talking to Photographs No, you dont have to be mad to talk to photographs. What is meant by “talking to photographs” is how images are judged and discussed. Being able to speak about a photograph, its technical content and what the image is trying to say is known as the ability to speak to a photograph. Why would we want to do this? This is how images are judged in photographic competitons and how images are discussed in reviews of exhibitions. If we know it exists then we can understand it. Exercise 13 You are to speak to 2 photographs. One of the photographs you will really like and the other you don’t. You need to explain why you like or don’t like the photograph and what you think the photograph is trying to say. Add this information to the document you created in exercise 9 and 10 and make sure you include the image and your comments. Have your lecturer go over your comments to ensure you have a full understanding of what talking to photographs is all about. 49 Section 3 Digital Darkroom Techniques There is a number of different software available for editing your digital images. All of them have similar basic features. We will investigate what these features are and you can then use the software of your choice to practice with these techniques. Save a Copy, never use the original All these images need storage in a way that we can find them again easily. We need to make a back up copy on a regular basis or we will loose our images. Digital Image storage can be done in many ways and it will be your personal preference that dictates how you store and back up your images. You can use chronological order which is my personal favourite. Keeping a folder for the year, then folders inside that year named after the events captured. Back up part or all of the year as needed. Alphabetically in folders explaining what’s inside the folder is another popular choice. Always copy onto some form of permanent storage your digital images. If your computer has to be rebuilt, gets infected with a data eating virus or hard drive fails you don’t want to loose all of those precious memories. DVD or CD backup is popular. I also have an external hard drive that I use as a storage device for all original images. When working with images never adjust the original. You never know when you might want to use it in its original form. Always open the original, save as a different file and then work on the copy of the file. Rotate Sometimes our photography isn’t perfect and we might need to rotate and image to straighten the image up a bit. All editing software that I know of has this facility usually found in conjunction with the crop tool. Figure 1 original image unedited 50 Figure 2 Image cropped and rotated Crop Cropping an image allows you to zoom into the part of the image that you want to use, removing the unwanted components of the image. The crop icon is found in all software and easily recognisable. You drag and drop the crop tool on the image, then adjust the edges until you’re happy with your crop. Then accept the changes and wallah, its cropped. If your crop tool allows rotating at the same time you will find your cursor changes when hovering around the corner of the crop window to a 90 degree bent arrow. Simply drag the corners using this arrow to rotate the crop area. Correct Colour and Tone Your editing software will give you options to correct contrast, brightness, and sometimes colour casts and mid tones. These features will allow you to correct exposure and lighting problems. Different software handles this area differently, some with wizards that do most of the work for you and some with manual features that you can adjust yourself. Exercise 14 Using some of your own images and the software package of your choice, practice with the crop, rotate and colour correction features. 51 Repair and Restore Some of the more complicated editing software allows you to repair and restore images. This feature is excellent when wanting to fix problems with faded, damaged and old photographs. Each software has its own tools to do this. Some experimenting is required when learning how to use these tools. Remember to always make a copy of your original image before you start to edit it. Exercise 15 Using an old or damaged image practice using the repair and restore features on your software package. Cosmetic Improvements We all know the magazines improve the look of their models but so can we. Similar to the repair and restore features of software there are also tools that you can use for cosmetic improvements. From revitalising the colours in photographs to softening skin tones, removing wrinkles and whitening teeth to improve the look of portraits. The more comprehensive software packages have these features. With the restore and repair tools, you will need to experiment and practice to master their use. Exercise 16 Using a photograph of your own experiment with the cosmetic improvements tools in your software package. Search the internet for tutorials specific to your software package. Save Your Working File Each of the more complicated software packages will have their own file format that will save additional information that will help you to continue working on an image, retaining file specific information such as layers etc. Always save your working file regularly, particularly when you have your image to a point that you’re pleased with it. Resize or Resample Want to resize an image so that you can print it larger. That should have been a consideration at the time of taking the photograph. Sometimes things happen and we cant get a better quality image to use. But if you have a great image but it will only print really clearly to 20cmx25cm and want to make it larger you need to look at resampling and 52 resizing the image. There is specific software available to do this for you or you can investigate the resampling options within the software that you are using. For more information about this go to http://graphicssoft.about.com/ cs/resolution/a/increasingres.htm Exercise 17 Try resampling and resizing one of your own images. Download some free upsampling software from the internet and try it out. How well did it work? Unsharp Mask We can use UnsharpMask (USM) to improve the sharpness of our images. Many software packages, scanning software and camera software comes with this feature. For detailed information about how and why it happens go to http://graphicssoft.about.com/gi/dynamic/offsite.htm?site=http%3A%2F %2Fwww.photoxels.com%2Ftutorial_sharpen_display.html Save a Copy for Final Output If your going to print or use your images outside of the software package that you have been using you will need to save a final version of your image in a format that can be used for printing. Most good print houses can print in either TIFF or JPG format. JPG format seems to be the most common. If you have done a lot of manipulation of the image, save your working file just in case you wish to use it again at a later date. Online Resources for learning Specific Software Packages Specific to this book you will find resources at www.melneumann.com/ studentzone. This site gives many video tutorials with files you can work on for all that we have discussed in section 3 of these notes. Photoshop: http://graphicssoft.about.com/od/photoshop/l/bllps5out.htm Paint Shop Pro http://graphicssoft.about.com/od/digitalphotography/a/10stepprep.htm and follow the links for paint shop pro tutorials. 53 Section 4 Output of Images So we have a fantastic collection of electronic images. We often show people on our computer some of what we have taken, as well as fantastic restorations, manipulations and enhancements that we have made. We may be very impressed with what we have done that we want to make it easy to show others. We used to carry around in our bag a packet of prints from the latest trip away, or the photos of our children that we brag to others about how absolutely beautiful these children are. We used to bluetac these prints to our work station walls, put them in frames or enlarge them and hang them on our walls and in galleries. Electronic images seem to be a bit like the old fashion slides. We need a slide show to show them to others. Of course we can create slide shows electronically and email them to our friends but how can Grandma show her friends her brag book in this day and age??????? Take your pick of options. There are some very exciting things that we can do with our photographs, especially now we understand the finer points of photographing and enhancing our images. Prints What a good idea. Let’s print our photographs. We could then put them in an old fashion style of album, frame them, give them to our friends, stick them on the fridge with magnets. All the things we use to do with prints from negatives. But how do we go about printing our photographs. There are a number of ways we can print our images. We can use online services where we upload, order and pay for prints online. They then arrive in the mail a few days later. Exercise 18 Go to www.kodak.com.au and have a look at the different printing services and pricing that is available. Have a look at some of their special printing options like printing on to mugs, t-shirts etc. 54 We can use a Digital Imaging Kiosk. These little machines allow us to take our images on USB drives/CD/ memory stick and print them on the spot for a very small charge. This type of service has replaced the minilabs such as fujifilm, Rabbit Photo and Kodak Express previously found in almost any shopping centre. They would process your film, print your film, do reprints and enlargements. We will also find these digital imaging kiosks in places like Harvey Norman, Foodland, Kmart etc. Exercise 19 Search the internet for a Digital Imaging Kiosk near where you live. Visit the Kiosk and see what services they provide. How different are the services in comparison with there online counterparts. We can print the images on our home printer. Some digital cameras have Docking Printers which is a printer that the camera attaches to. They will print 6inx4in prints directly from the camera on to specially designed photographic paper. Kodak have a fantastic array of cameras with docking station. This is something that we should consider when buying a camera. Most well known brands now have the docking style printers for their range of cameras. Exercise 20 Have a look at some of the digital camera sites and see what companies have dockable printers that will print 6x4in prints directly from the camera. Do the cameras that we looked at earlier have dockable printers? What are some of the features that these types of printers come with? We can print larger prints from our home printers, up to A4 size in most cases for home users. We can purchase special photographic paper for use with the printers. We sometimes find what we see on our computer screen doesn’t match completely with what is printed. This colour matching problem can be improved by calibrating the monitor to the printer. See your printer and computer documentation guide to see if this is possible. The quality of home printers will dictate the quality of the print. For that special print you might consider one of the other options. Exercise 21 See what you can find on the internet about the life span of photographic paper. Find out about etching paper and canvas that digital prints can be printed on. 55 We can go to a Professional Printing Service who deals with professional images. They will not only print our images but colour correct, crop, frame, and laminate our images for display. They are able to do extremely large prints as long as the quality of the image is ok. They will be able to advise you on other possibilities like using filters to create art like images or other printing options such as printing on to canvas, art papers, etc. The final cost of the image is often more but the service and quality can make a big difference. Exercise 22 Go to www.atkinstechnicolour.com and have a look at their price list to see the types of professional services available from a professional photographic lab and the prices that they charge. How different are their prices from the Digital Imaging Kiosks? Making Books The most incredible phenomenon in presentation of images is the growing interest in coffee table style books. There are a number of companies that will print an entire book or your creations and bind them into a very impressive hard cover book. This can be done online at places like www.kodakgallery.com, by downloading free software such as at www.momento.com.au, or buy using software such as Adobe’s Photo Album software and then taking the finished file to companies such as www.digitaldavinci.com.au. A sense of design and creativity will help you to develop fabulous creations, fantastic gifts and life long memories that can be passed down. There are also services available that will do the design and creativity part of the process with your images. Exercise 23 Download the free software from www. momento.com.au and try out the software to create a book of your own. Try out some of the different options available in the software. Create a book of some of the images you have created in this course. Have a look at the www.kodakgallery.com site and look up books. Try that process to compare the two processes. If you are using a Mac, go to www. digitaldavinci.com.au and download the free software for MAC albums and compare that to the kodakgallery site. 56 The other very popular book idea is digital scrapbooks. This is an electronic version of the very popular scrap booking craze. Again a very creative way to display your images. Exercise 24 Look up the term Digital Scrapbook on the internet. Find out what its all about. When could you see a viable option for scrap booking your images? Electronic Slide Shows and screensavers. There are many software products that will take still images and make them into electronic slide shows or screensavers. Slide shows often use music and transition, motion and special effects to create interesting electronic slide shows. We can then use these to email to friends, put onto CD or DVD, add to media devices such as picture viewers and video Ipods etc. This is an excellent way to create a presentation for many purposes. Exercise 25 We will use Microsoft’s moviemaker to create a simple yet effective video slide show. • Choose a series of images to use for your slideshow. Place the images into a folder on their own. Select some music for the presentation and put that also in the folder. • Open Moviemaker.(start>>accessories>>movie maker). • Under movie tasks 1.Capture Video select Import pictures. Browse to your folder with your selected images and import the images. They will be seen in the collections window. • Import An audio/music track to put on your slide show. • Under the movie task 2.Edit Movie select the Make and AutoMovie option • Select the music video options, add a title and select the background music in this area • When you have it as you would like select done, edit movie.You will have a completed slide show which you can now use the transition and effects windows to make changes to your slide show. • Use the finish movie settings to experiment with different ways of exporting your movie. The wizards that are available in this program make it easy to put together a presentation easily and quickly. For software that allows more options you would need to learn a video editing software package. The Movie Maker software is great fun. Experiment with its different options and see what you can create. Visit the companion web site for this set of notes to view a video tutorial on this exercise. 57 Exercise 26 We can also create screensavers of our images and display them on our computer screens. http://www.webshots.com/samplers/ has free software that will allow you to create your own screensavers from any group of photos or images files you like. Using some of the photographs you have created make a screensaver for you desktop. Apart from creating electronic slide shows and screensavers we can now buy image previewers. These are electronic devices with hard drives that can store images and create slide shows for us. These devices are small enough to carry around in our handbag, as good as looking at images that have been printed. The Epson Multimedia storage viewer is an excellent example of what is available. Go to http://www.epson.com.au/products/multimedia/p2000. asp and have a look at the specifications for this device. It will view still and video images, including sound etc. A cheaper alternative is the Kodak Easyshare picture viewer. Go to the Kodak web site and find out information about this product. Exercise 27 Compare the two viewers mentioned and create a matrix like we did with the digital cameras to see what would be the best option for you to purchase. Search the internet and find other brands of picture viewers. Online Galleries There are many areas on the internet that allow you to use space to create an online gallery. Many of these galleries allow you to upload and invite others to view your images. Go to www.kodakgallery.com and see what services they have available to members. Another online gallery that offers space is http://www.deviantart.com. This site is very different to the Kodak site for a number of reasons. The Kodak site is very commercial and offers many additional features such as being able to order prints online etc. this site is great because of all of the other services it offers. 58 Deviant art is a fantastic site to get comment about your photography. It is more about the photographic images as it offers limited other services but is a community of like minded photographic creators. It also has some fantastic examples of other peoples art work which can inspire us to do better. 59 Section 5 Where to now? Well we have come to the end of this journey. There are many things you can do from here. You can continue to practice all that we have discussed in these notes. Practice using the different features of your digital camera. Practice the use of lighting and composition techniques. The more photographs you take the better you will get at taking them. Dont be afraid to experiment with your digital images and play with the different mode settings your camera has. Your next step would be to manipulate your images further. Editing software will allow you to manipulate and bring out the best in your images but some software is limited in what it can do. There are a number of excellent books and web sites that provide tutorials on most of the popular photographic software editing tools. My tool of choice is Photoshop and it is currently the industry standard. There are many fine publications that I recomend for learning photoshop which you will find on the companion web site for these notes. The companion web site is www.melneumann.com/studentzone. This site will be continually updated and will provide further information as to resources that myself and my students have found useful. Please also feel free to email any additional information about sites you have found useful and we will include them on the web site. I hope you have enjoyed Capture a Digital Image. Keep On Snapping!! Mel 60 61 About the Photographs There are many images used in this publication. The following is details about the photographers and what camera the images were taken using. Melissa Neumann Adelaide photographer Melissa Neumann has been a photographer since 1991, with Children being her main specialty. Mel has won many Australian Awards for her photographic work. She is now a retired member of the Australian Institute of Professional Photography, was the State Present for 2 years and was an Associate Member for many years. Melissa has the honor of having one of her images being accepted in to the 1994 Loan Collection in the American Professional Photography Awards. This image is now, I believe, in the New York Metropolitan Museum of Modern Art, New York’s collection. Melissa returned to Study in Information Technology in 1998 and her main employment is with TAFESA as a lecturer in multimedia, teaching photographic concepts and photographic manipulation, web development, basic video production, as well as other areas of Multimedia. Her main interest still lies in photography and photographic art. She enjoys teaching others about the fun you can have with digital cameras and is determined to improve others photographic abilities by making resources she has created avalable to the world free of charge.
